Using two or more host templates to aggregate contacts

Hi all,
I'm trying to configure nagios 3.0.6 so that I can add contact groups to a
host by adding a host template to the host definition.
I have one host template called 'unix-host' that I'm using to aggregate the
Unix Team contacts into a template. I have another host template called
'oncall-host' that I'm using to represent people on call 24x7. If a host is
critical enough that the on-call people should be alerted if it goes down, I
want to be able to add the 'oncall-host' host template as a template for the
critical host, have the 'unix-host' host template as another template for
the host, and have nagios alert both the people on call and the Unix Team
admins if the host goes down. The on-call people should be alerted by SMS
and email every 5 minutes, but the Unix Team admins are should only be
alerted by email every 10 minutes.
I have an email server called 'doris' that is currently down, and is
configured as specified below. What's happening is that the on-call people
are being alerted by SMS and email every 10 minutes (which is as it should
be), but the Unix Team admins aren't being alerted at all. If I remove the
'oncall-host' template from the host definition, the Unix Team admins are
alerted by email as they should be.
Can anyone suggest how I might get the alerting working, and still be able
to just add the 'oncall-host' template as a template for a critical host?
Perhaps it would be better to do this with hostgroups?
Here are all my definitions... sorry if it's a bit convoluted:
Here's the host definition for the host in question:
define host {
host_name doris
alias doris email server
address 192.168.2.25
parents sw-l3-mail
use oncall-host,unix-host
register 1
}
'unix-host' host template:
define host {
name unix-host
alias Unix Team host template
use generic-host
contact_groups +unix-admin
register 0
}
'oncall-host' host template:
define host {
name oncall-host
alias Host template for critical
hosts
use generic-host
contact_groups oncall-primary
notification_interval 5
register 0
}
'generic-host' host template:
define host {
name generic-host
alias Top-level host template
check_command check-host-alive
max_check_attempts 10
check_interval 5
retry_interval 1
active_checks_enabled 1
check_period 24x7
obsess_over_host 1
check_freshness 1
event_handler notify-host-by-email
event_handler_enabled 1
flap_detection_enabled 1
process_perf_data 1
retain_status_information 1
retain_nonstatus_information 1
notification_interval 10
notification_period 24x7
notification_options d,u,r
notifications_enabled 1
failure_prediction_enabled 1
register 0
}
'unix-admin' contact group:
define contactgroup {
contactgroup_name unix-admin
alias Unix Team Admins
members nagiosadmin
}
'oncall-primary' contact group:
define contactgroup {
contactgroup_name oncall-primary
alias On-call Primary
members oncall_phone1
}
'nagiosadmin' contact:
define contact {
contact_name nagiosadmin
alias Nagios Admin
contactgroups unix-admin
email nagiosadmin at mydomain.co.uk
use human-contact
}
'oncall-phone1' contact:
define contact {
contact_name oncall_phone1
alias On-call Phone #1
contactgroups oncall-primary
email phone1 at mydomain.co.uk
pager 07555555555
use oncall-contact
}
'human-contact' contact template:
define contact {
name human-contact
alias Human contact template
contactgroups unix-admin
host_notification_period 24x7
service_notification_period 24x7
host_notification_options d,u,r
service_notification_options w,u,c,r
host_notification_commands notify-host-by-email
service_notification_commands notify-service-by-email
use generic-contact
register 0
}
'oncall-contact' contact template:
define contact {
name oncall-contact
alias On-call contact template
contactgroups oncall-primary
host_notification_period 24x7
service_notification_period 24x7
host_notification_options d,r
service_notification_options u,c,r
host_notification_commands
notify-host-by-email,notify-host-by-sms
service_notification_commands
notify-service-by-email,notify-service-by-sms
use generic-contact
register 0
}
'generic-contact' contact template:
define contact {
name generic-contact
alias Highest-level contact
template
host_notifications_enabled 1
service_notifications_enabled 1
host_notification_period 24x7
service_notification_period 24x7
register 0
}
Regards,
Guy.
